Ok everyone,I need some input.The original antenna is old and cracked.I can either source out a new OEM one or use a FIN.

We will paint the FIN the same colour as the car and re-assess.Initially I didn't like it, but then it started to grow on me. After seeing a number of other cars with fins after leaving the shop, it fits in line with them.

I like the fin, it fits the car well. There is something to be said about keeping the car factory with what originally came on there, but little additions like that look really good when chosen properly.
